Co-occurrence network and functional prediction analysis: a co-occurrence network of the control group KO; b co-occurrence network of the FC group; c co-occurrence network of supplementation with high-dose dose of Chinese medicine. Blue indicates positive correlation, red indicates negative correlation. The numbers of nodes and links indicate the tightness of the connection between the bacteria and others, indicating the strength of the symbiotic relationship; d functional gene abundance for the intestinal microbiota; e analysis of gene difference between FC and GA groups
